Transfusion of Prematures (TOP) Trial: Does a Liberal Red Blood Cell Transfusion Strategy Improve Neurologically-Intact Survival of Extremely-Low-Birth-Weight Infants as Compared to a Restrictive Strategy?

NICHD Neonatal Research Network·interventional·Posted Oct 8, 2012·Updated Nov 14, 2025

In Brief

A clinical study evaluating Liberal Cell Transfusion and Restricted red cell transfusion for Infant, Newborn, Diseases and 4 related conditions. Completed, enrolled 1,824 participants across 20 sites.

Detailed Summary

The objective of the TOP trial is to determine whether higher hemoglobin thresholds for transfusing ELBW infants resulting in higher hemoglobin levels lead to improvement in the primary outcome of survival and rates of neurodevelopmental impairment (NDI) at 22-26 months of age, using standardized assessments by Bayley.
